To provide a heat recovery device that makes a circulation of a heating medium smooth and relaxes stress concentration, with respect to a structure where flat-shaped tubular member in which the heating medium circulates is bonded to a burring part.

In a core of heat recovery part of a waste heat recovery, a burred opening is formed on a lower plate 37d of a casing, and a flat-shaped tube 34 is inserted into and brazed the burring part 71. In a bending section of the burring part 71, the radius of curvature of a side section 71a is set larger than that of a front-and-rear end section 71b. The rigidity of the side section 71b of the burring part 71 is thereby increased and the rigidity on each part of the burring part 71 is equalized.
